gigantopithecus blacki
Gigantopithecus is an extinct genus of ape that existed from roughly one million years to as recently as three hundred thousand years ago, in what is now China, India, and Vietnam, placing Gigantopithecus in the same time frame and geographical location as several hominin species. The fossil record suggests that individuals of the species Gigantopithecus blacki were the largest apes that ever lived, standing up to 3 metres (9.8 ft). Due to wide interspecies differences in the relationship between tooth and body size, some argue that it is more likely that Gigantopithecus was much smaller, at roughly 1.8 m (5.9 ft). Recent estimates of its body mass suggest a weight of 200–300 kg (440 - 660 lb). The species lived in Asia and probably inhabited bamboo forests, since its fossils are often found alongside those of extinct ancestors of the panda. Most evidence points to Gigantopithecus being a plant-eater. Its appearance is not known, because of the fragmentary nature of its fossil remains. It is possible that it resembled modern gorillas, because of its supposedly similar lifestyle. Some scientists, however, think that it probably looked more like its closest modern relative, the orangutan. Being so large, it is possible that Gigantopithecus had few or no enemies when fully grown.
epicyon haydeni
Epicyon ("near dog") is a large extinct canid genus of the subfamily Borophaginae ("bone-crushing dogs"), native to North America. It lived from the Hemingfordian age of the Early Miocene to the Hemphillian of the Late Miocene (20.6—5.330 Mya. Epicyon existed for about 15.5 million years. Epicyon was one of the last of the Borophaginae and shared its North American habitat with other canids: Borophagus (23.3—3.6 Mya), Paratomarctus (16.3—5.3 Ma), Carpocyon (20.4—3.9 Ma), Aelurodon (23.03—4.9 Ma), and the first emerging wolf, Canis lepophagus appearing 10.3 Ma. Epicyon was named by Joseph Leidy in 1858 as a subgenus of Canis. It was also mentioned as belonging to Aelurodontina by William Diller Matthew & Stirton in 1930. Fossil specimens range from Florida to Alberta, Canada to California; from Nebraska, and Kansas to New Mexico and Texas. Epicyon haydeni existed for 15.3 mya It is synonymous with Aelurodon aphobus, Osteoborus ricardoensis, Osteoborus validus, Tephrocyon mortifer) was named by Joseph Leidy as a subgenus. It was recombined as Aelurodon haydeni by Scott and Osborn in 1890. Further study by Matthew in 1899, Matthew and Gidley in 1904, VanderHoof and Gregory in 1940, McGrew in 1944, Bennett in 1979, (1979) and Becker (1980). It again was recombined as Epicyon haydeni by Baskin in 1980, Voorhies in 1990, (1990), Baskin (1998), Wang et al. in 1999. Morphology: The largest known specimen weighed an estimated 170 kg (374.8 lbs).
